Application October 8, 1956, Serial No. 614,538

lo'Claims. '(Cl. 5|1'06) This invention relates to improvements in a reclining chair wherein a seat and back-rest, and also a leg-rest if one be employed, may be swingable and/or shiftable between sitting and reclined positions relative to a support.

This application is a continuation-in-part of the application bearing Serial Number 448,439 and filed by me on August 9, 1954, now Patent No. 2,778,408 of Jan. 22, 1957.

The invention contemplates a novel article of furniture having multiple coacting components which are relatively spaced on and are'swingable relative to a suitable support means whereby the components may be easily actuated by the occupant so as to move same between a normal upright or sitting position and one of a multiplicity of reclining positions. In assuming the reclining position, a back-rest is swingable realwardly relative to the support to bring about the angularization of a seat member relative to a support and simultaneously to bring about the swinging and/or shifting of a leg-rest, if one be employed in the structure, relative to the angularization of the seat.

More specifically, this invention envisions a reclinable chair comprising a support, a seat, a back rest, and a guiding link wherein the latter three components are swingable relative to one another and are also swingable relative to the support.

Additionally, the inventioncontemplates a structure wherein the multiple coacting elements above defined may be combinable with a leg-rest and its related operating components. In which instance, as the swingable seat is angled upwardly relative to its swingable connection with the support upon the reclination 'of the back-rest, the leg-rest, which is spaced from and is without direct attachment either to the seat or to the support, is shifted rapidly away from the forward portion of the seat in a manner whereby the leg-rest is extendable concomitantly downwardly and outwardly and subsequently concomitantly forwardly and upwardly relative to the angular movement of the seat. In this manner, improved body support throughout the entire cycle of positions assumed between the forward sitting position and the rearward reclining position and vice versa is achieved.

It is an object hereof to provide an improved leg-rest support means whereby 'the occupants body is held in constant support throughout the cycle of movement thereof due to the accelerated progressive spacing of the legrest relative to the angularization of the seat and backrest. This support is attained continuously from the initial movement of the leg-rest away from its normal vertical position, when the chair components are in the sitting position, to the time when it assumes a substantially horizontal position, when the chair components are in the reclined position.

The resultant effect is an improvement over the effects attainable with known prior art devices due to certain limitations of prior art devices which are herein over- COHE- lee Additionally, the components hereof are held inpoised balanced relationship with the support so as to make maneuverability of the movable body supporting members possible with a minimum of effort and a maximum of ease.

An object hereof is to provide a reclinable structure. wherein the resistance or friciton devices for holding the components in various relative positions, so objectionable in known prior art structures, are eliminated.

Another object hereof is to provide a novel connecting means for the counterbalancing of the shiftable body supporting members, which means is engaged with the support within a more-'or less concentrated or confined area approximately intermediate the leg-rest and the back-rest so as to provide an exceptionally well poised balance between the body supporting members in their various related positions, all without any necessary additional employment of any guiding means connected to the support. That is to say, the swingable connections between the seat and the support and between the back-rest and the support are the only direct connecting means with the support. Such a feature contributes effectively toward trouble-free operation in a manner readily recognizable by those familiar with the art.

In the accompanying drawings, I have illustrated seve'ral'complete examples of the invention wherein the elements are combined and coact in accordance with a fundamental principle of design toward which I have directed my invention. However, changes and alterations are envisioned and may be such as to modify the structures illustrated in the "exemplifying drawings herein and yet to remain within the scope of the claims appended hereto.

In thedrawings:

Fig. 1 is a combined partial side elevational view and longitudinal sectional view from the inside face of the near side wall of the chair of the invention showing an upright sitting position of the'components thereof by solid lines and a rearward reclined position thereof by dash lines;

Fig. 2 is a combined partial side elevational view and longitudinal sectional view taken'froin the inside face of the near side wall of a chair showing another form-of the structure of the invention shown in Fig 1.

Fig. 3 is a combined partial side elevational view and longitudinal sectional view taken from the inside face of the near side wall of a chair showing another form of the structure shown in Fig. 1;

Fig. 4 is a fragmentary side elevational view with certain parts in section showing the connecting means between the seat and the guiding link; and

Fig. 5 is a sectional view on the line 5-5 of Fig. 4.

Referring now to the drawings more in detail, the chair structure will first be described. I have shown, in Fig. 1, a support, generally designated by the numeral 2, which consists of a pair of transversely-spaced parallel vertically=extending side wall members 4 and 5, which members 4 and 5 are rigidly connected together by a plurality of transverse members such as 6 and 8, as is conventional.

The chair components may be made of wood or metal or other equivalent materials and may be suitably padded or upholstered or otherwise covered in any suitable manner.

A back-rest, generally designated by T0, is swingably mounted on the support 2 at 12 intermediate the upper and lower extremities of the back-rest to define a portion of the back-rest herein referred to as a back-rest extension 13 which is disposed downwardly of the swingable connection 12.

A seat 14 is 's'wingably mounted on the support 2 'at 16 at a point remote from the connection 12 between the back-rest 10 and the support 2 wherefor the back-rest 3 and seat are movable in variable degrees relative to each other.

The back-rest and the seat may each consist of a framework comprising the usual pair of spaced parallel side rail members (represented by 18 in the case of the backrest and by 20 in the case of the seat) and a plurality of transverse rail members (represented by 22 in the case of the back-rest and by 24 in the case of the seat) connecting therebetween at appropriate spaced intervals. Conceivably, the back-rest, seat, and leg-rest if employed, could otherwise comprise solid unitary members should same be desired, all without affecting the spirit of this invention.

The swingable connections 12 and 16 may comprise in each case a pair of coaxial pivot members or a unitary rod member extending from side wall member 4 to side wall member 5.

The seat 14 may be provided with projecting portions 26 extending upwardly from the opposite side rail merribers 20 and 20 as shown. Conceivably, brackets could be fixed to the upper sides of the members 20 and 20 so as to provide an equivalent result or function, which result or function will hereinafter appear.

A stop member 21 fixed to the opposite side wall members 4 and of the support 2 may support the seat 14 in the sitting position in the conventional manner.

The topmost portion 8 of the transverse member 8 may function as a stop against which the back-rest may abut when the structure is in the extreme reclined position in the well-known manner.

Throughout all of the views and the specification, only one of the linkage systems will be shown and/ or described, all for purposes of simplification. It will be appreciated, however, that duplicate linkage systems may be readily employed on opposite sides of the structures hereof, which systems operate in unison, all in a manner and for purposes well known in the art.

A stationary link on the side wall member 4 and 5 of the support 2 is indicated by the bracket designation 28 and connects the swingable connection 16 of the seat and the support and the swingable connection 12 of the back-rest and the support. The stationary link connects the swingable connections 12 and 16 which coact as a dual fulcrum. As above explained, corresponding stationary links are provided on opposite sides of the support so that dual fulcrums on each side of the chair are provided. Same constitute the only connecting means between the support 2 and the other components of the structure, as aforesaid.

An actuating link 40 is provided having a rear end portion thereof swingably connected at 42 to the lower extension 13 of the back-rest 10. Link 40 is also swingably connected at 44, adjacent its forward end, to the lower end of a primary connecting link 46.

The upper end of the primary connecting link 46 is swingably connected at 48 to the seat 14. Connection 48 may be located at any point on the seat 14 forwardly of the connection 16.

Link 40 is also swingably connected at 50, intermediate its opposite ends and at a point remote from connections 42 and 44, to the lower end of a guiding means 52.

The upper end of the guiding means 52 is swingably mounted at 54 on the projecting portion 26 of seat 14.

It will be observed that the swingable connections 12, 16 and 54 are relatively disposed in a novel manner. The axes of the connections 12, 16 and 54 are relatively spaced as to each other and the axes of the connections 16 and 54 are relatively spaced in reference to the seat.

A vertical plane extending through the longitudinal axis of the connection 12 is spaced horizontally away from and rearwardly of a plane parallel thereto extending through the longitudinal axis of the connection 16.

Actuating link 40, primary connecting link 46, guiding link 52, extension 13 of the back-rest 10, and stationary link 28 of the base 2 constitute the control means whereby control of the movement of the seat is attained upon reclination of the back-rest.

Additionally, a primary link 56 is provided having one end thereof swingably connected at 58 to the forward extremity of link 40 and having its opposite end swingably connected at 60 to one end of a secondary link 62. The opposite end of secondary link 62 is swingably connected at 64 to a leg-rest, generally designated by 66.

Leg-rest 66 is of familiar design and function and may include the usual vertically spaced side rails 67 and transverse connecting rails 67 therebetween. If desired, the leg-rest may comprise a solid unitary member without departing from the spirit of the invention.

The leg-rest is normally positioned in a substantially vertical position as is conventional.

Primary connecting link 46 additionally is swingably connected at 68 to one end of a secondary connecting link 70. The opposite extremity of secondary connecting link 70 is swingably connected at 72 to primary link 56.

It will be understood that the secondary connecting link 70, While being shown herein as positioned below the actuating link 40, may be disposed above the actuating link and still be swingably associated with members 46 and 56 with equally effective results. In such instance, primary link 56 would be provided with a rigid extension reaching above the pivot 58 whereat the swingable connection 72 might be suitably provided.

Whether the secondary connecting link 70 is disposed below or above the actuating link 40, a pantograph-like or quadrilateral linkage is formed by the members 40, 46, 56 and 70 for purposes subsequently to be described.

A tertiary link 74 is suspended from and swingable on the seat 14 at 76 and is swingably connected at 78 to a quadrary link 80. The quadrary link 80 has one end thereof swingably connected at 82 to the leg-rest 66 at a point spaced from the connection 64.

Quadrary link 80 is provided with a rigid extension 84 which is swingably connected at 86 to the primary link 56 whereby the primary and secondary links, 56 and 62 respectively (hereinafter identified as the first pair of links), and the tertiary and quadrary links, 74 and 80 respectively (hereinafter identified as the second pair of links), are connected so as to produce coordinated movements of the first and second pairs of links.

Connections 44 and 72 of the pantograph-like linkage aforementioned function as centers having a certain center-to-center longitudinal distance therebetween when the chair structure is in the sitting position. Said certain center-to-center distance increases or expands as the chair components swing into the reclining position. As the distance expands, the resultant effect is to increase the acceleration and to extend the travel of the leg-rest relative to the angularization of the seat and back-rest.

That is to say, the pantograph linkage coordinates the movement of the leg-rest with the inclining of the seat. Additionally, it accelerates the rate of shifting of the legrest relative to the rate of inclination of the seat by virtue of the unique control which it exercises over the movement of the said two pairs of links.

In a few words, the rate of the inclining movement of the seat is less than the rate of the shifting movement of the leg-rest.

As the back-rest swings to reclining position, the seat is angularized and the leg-rest is shiftably swung downwardly and forwardly and subsequently outwardly and upwardly relative to the seat.

The reclination of the back-rest controls the positioning of the seat through the coacting movement of the actuating link and primary connecting link and guiding link. Simultaneously, the reclination of the back-rest controls the positioning of the leg-rest as the said center-to center distance of the pantograph-like linkage progressively expands or increases by the acceleration of the rate of the shifting and swinging of the leg-rest.

As aforesaid, the rate of the shifting of the leg-rest is relative to the rate of the swinging of the seat.

As is known in the prior art, it is during the initial stages of the movement of the leg-rest that continual support of the legs of the occupant is -lacking. Herein, the shifting of the leg-rest is appropriately timed with the reclination of the back-rest and with the angularization of the seat .so as to insure constant support of the torso, thighs, and lower leg portions of the occupant. Whether in reclining or declining movements, the related positioning of the leg-rest and back-rest are retained in the desired poised balance.

When .a chair occupant leans his body weight against the back-rest so as to swing same around its swingable connections into the reclined position shown in the dash lines, the seat and the leg-rest may be brought into their respective positions by means of the link mechanism described above. The back-rest may even extend therebeyond to the extreme position whereat the back-rest abuts the top 8' of the transverse member 8 and the seat and leg-rests are simultaneously moved to their extreme positions.

The path of travel of the leg-rest from the sitting position to the reclining position may be recited as follows: Initially, the leg-rest juts downwardly relative to the initial angular incline of the seat so as to commence the elongation of the space between the front of the seat and the top of the leg-rest and thereby increase the spread of the support offered to the occupants legs below his knees. That is, the movement of the leg-rest commences away from the seat simultaneously with the inclining movement of the seat upon the reclining movement of the back-rest. As the seat continues to incline, the leg-rest shifts forwardly relative thereto so as to continue the elongation of the space from the seat to offer added leg support to the occupant. As the seat inclines still further, the leg-rest extends further forwardly and upwardly whereby still increased spread for leg support is realized.

The form of the invention shown in Fig. 2 will now be described.

As in the case of the form of Fig. 1, a support 102 includes side wall members 104 and '105 connected together by transverse members such as 106 and 108.

A back-rest 110 is swingably mounted on the support 102 at 112 and has a rigid back-rest extension 113 downwardly of the connection 112. The back-rest may include spaced side rail members 118 and transverse rail members 122.

A seat 114 is swingably mounted on the support 102 at 116 at apoint remote from the connection 112 between the back-rest 110 and the support 102. The seat may include side rail members 120 and transverse rail members 124 and is provided with projecting portions 126 extending upwardly from the opposite side rail members 120 and 120.

A stop member 121 is fixed to the opposite side wall members 104 and 105 of the support 102 and supports the seat 114'in the sitting position. A topmost portion 108 of the transverse member 108 may function as a stop against which the back-rest 110 may abut when the structure is in the extreme reclined position.

A stationary link on each of the side wall members 104 and 105 of the support 102 is indicated by the bracket designation 128 and connects the coacting swingable connection 116 of the seat and the support and the swingable connection 112 of the back-rest and the support whereby a dual fulcrum is provided.

The dual fulcrums on the opposite sides of the chair structure constitute the only connecting means between the support 2 and the other components of the structure.

An actuating link 140 is provided having a rearward end portion swingably connected at 142 to the lower extension 113 of the back-rest 110. Same is also swingably connected at 144, adjacent its forward end portion, to the lower end of a primary connecting link 146. The

6 upper end of the primary connecting link 146 is swingably connected at 148 to the seat 114. Actuating link 140is also swingably connected at 150, intermediate its opposite ends and at a point remote from the connections 1'42'and 144, to the lower end of a guiding means 152.

The upper end 'of the guiding means 152 is "swingably mounted at 154 on the side railmember of the seat 114 at a point below and forwardly of the connection 116.

It will be observed that, in the form of the invention disclosed in Fig. 2, the swingable connections 112, 116 and 154 are relatively disposed in a novel manner. Vertical parallel planes through longitudinal axes of the connections 112, 116 and 154 are spaced with the vertical plane through the axis of connection 154 being disposed outside of and being parallel to the parallel planes of -the axes of the connections 112 and 116.

Stated otherwise, a vertical plane extending through the longitudinal axis of the connection 112 is spaced horizontally away from a plane parallel thereto which extends through the longitudinal axis of the connection 116. Another verticalplane through the longitudinal axis of connection 154 is also parallel therewith and is spaced horizontally of the said vertical planes through the longitudinal axes of the connections 112 and 116.

As in the form of Fig. 1, actuating link 140, primary connecting means 146, guiding means 152, extension 113 of the backrest 110, and stationary link 128 of the base 102, on each side of the chair structure, constitute the control means whereby control of the movement of the seat is attained upon reclination of the back-rest.

Additionally, one end of a primary link 156 is swingably connected at 158 to the forward extremity of actuating link and the opposite end thereof is swingably connected at 160 to one end of a secondary link 162.

The opposite end of the secondary link 162 is swingably connected at 164 to a leg-rest 166 which includes the usual side rails 167 and transverse connecting rails 167".

Primary connecting link 146 is also swingably connected at 168 to a secondary connecting link 170. The opposite extremity of the secondary connecting link 170 is swingably connected at 172 to the primary link 156.

' A pantograph-like or quadrilateral linkage is formed by the members 140, 146, 156 and 170.,

A tertiary link 174 is swingably connected to the seat 114 at 176 and is swingably connected at 178 to a quadrary link 180. One end of the quadrary link 180 is swingably connected at 182 to the leg-rest 166 at a point spaced from the connection 164 of the secondary link 162 and leg-rest 166. Quadrary link 180 is provided with a rigid extension 184 which is swingably connected at 186 to primary link 156 whereby the primary and secondary links, 156 and 162 respectively (the first pair of links), and the tertiary and quadrary links, 174 and 180 respectively (the second pair of links), are connected so as to produce coordinated movements of the pairs of links.

The connections 144 and 172 of the pantogr-aph-like linkage previously described in connection with the disclosure of Fig. 1 function as centers having a certain center-to-center longitudinal distance therebetween when the chair structure is in the normal sitting position.

The related movements of the components are as aforedescribed in the case of the form of Fig. 1 hereof.

The form of the invention shown in Fig. 3 will now be described. 7

As in the case of the form of Fig. l, a support 202 includes side wall members 204 and 205 connected together by transverse members such as 206 and 208.

A back-rest 210 is swingably mounted on the support 202 at 212 and has a rigid back-rest extension 213 downwardly of the connection 212. The back-rest may include spaced side rail members 218 and transverse rail members 222.

A seat 214 is swingably mounted on the support 20-2 I at 216 at a point remote from the connection 212 be '5" tween the back-rest 210 and the support 202. The seat may include side rail members 220 and transverse rail members 224.

Seat 214 has projecting portions 226 extending upwardly from the opposite side rail members 220 and 220, as shown.

A stop member 221 is fixed to the opposite side wall members 204 and 205 of the support 202 and supports the seat 214 in the upright sitting position. The topmost portion 208 of the transverse member 208 may function as a stop against which the back-rest 210 may abut when the structure is in the extreme reclined position.

A satationary link on each of the side wall members 204 and 205 of the support 202 is indicated by the bracket designation 228. Same connects the coacting swingable connection 216 of the seat and the support and swingable connection 212 of the back-rest and the support and provides a dual fulcrum. The dual fulcrums on the opposite sides of the chair structure constitute the only connecting means between the support 202 and the other components of the structure.

An actuating link 240 is provided having a rearward end portion thereof swingably connected at 242 to the lower extension 213 of the back-rest 210. The actuating link 240 is also swingably connected at 244, adjacent its forward end portion, to a primary connecting link 246. The opposite upper end of the primary connecting link 246 is swingably connected at 248 to the seat 214.

The actuating link 2 40 is also swingably connected at 250, intermediate its opposite ends and at a point remote from the connections 242 and 244, to the lower end of a guiding means 252.

The opposite upper end of guiding means 252 is swingably mounted at 254 on the side of the rail member 220 of the seat 214 opposite from the side carrying the connection 216 between the seat and the support. That is to say, connections 216 and 254 are coaxial.

As more clearly shown in the fragmentary views in Figs. 4 and 5, the projection 226 is vertically slotted intermediate the width thereof so as to provide spaced shoulders upon which the connections 216 and 254 may be disposed.

It will be observed that, in the form of the invention disclosed in Fig. 3, the swingable connections 212 and 216 are relatively disposed in a novel manner. As shown, for illustrative purposes, vertical parallel planes through the longitudinal axis of connection 212 the coaxial longitudinal axes of connections 216 and 254 are spaced horizontally. Stated in another way, a vertical plane extending through the longitudinal axis of the connection 212 is spaced horizontally away from a plane parallel thereto which extends through the longitudinal axes of the connections 216 and 254.

As in the form of Fig. 1, actuating link 240, primary connecting means 246, guiding means 252, extension 213 of the back-rest 210, and stationary link 228 of the base 202, on each side of the chair structure, constitute the control means whereby control of the movement of the seat is attained upon reclination of the back-rest.

Additionally, a primary link 256 has one end swingably connected at 258 to the forward extremity of actuating link 240 and an opposite end swingably connected at 260 to one end of a secondary link 262. The opposite end of secondary link 262 is swingably connected at 264 to a leg-rest 266 which includes the usual side rails 267 and transverse connecting rails 267.

Primary connecting link 246 is also swingably connected at 268 to a secondary connecting link 270. The opposite extremity of the secondary connecting link 270 is swingably connected at 272 to the primary link 256.

A pantograph-like or quadrilateral linkage is formed by the members 240, 246, 256 and 270.

A tertiary link 274 is swingable on the seat 214 at 276 and is swingably connected at 278 to a quadrary 8 link 280. Said quadrary link 280 has one end thereof swingably connected at 282 to the leg-rest 266 at a point spaced from the connection 264 of the secondary link 262 and leg-rest 266. The quadrary link 280 is provided with a rigid extension 284 which is swingably connected at 286 to the primary link 256 whereby the primary and secondary links, 256 and 262 respectively, as the first pair of links, and the tertiary and quadrary links, 274 and 280 respectively, as the second pair of links, are connected so as to produce coordinated movements of the pairs of links.

The connections 244 and 272 of the pantograph-like linkage aforementioned function as centers having a certain center-to-center longitudinal distance therebetween when the chair structure is in the upright sitting position.

The related movements of the components are as aforedescribed in the case of the form of Fig. 1 hereof.

While I have illustrated and described the invention as embodied in certain specific arrangements, I do not intend to be limited to the details shown since various modifications and structural changes may be made without departing in any way from the spirit of the invention.
